Batch dependent safety (John Campbell)

Reports of Batch-Dependent Suspected Adverse Events of the BNT162b2 mRNA COVID-19 Vaccine: Comparison of Results from Denmark and Sweden
----------------------------------
Conclusions

The batch-dependent safety signal observed in Denmark and now confirmed in Sweden suggests that early commercial batches of BNT162b2 may have differed from those used later on, and these preliminary and hypothesis-generating results warrant further study.



The later batches were less dangerous than the earlier batches. Did they water them down, or put in a lot of saline doses to fill out their orders?
